LifeViewer/Known bugs/Scripting

Currently known issues with LifeViewer script commands.

• STATE1FIT does not work as expected in [R]Super rules.
  • STATE1FIT may be deprecated in the future in favor of a new ALIVEFIT command in order to resolve this issue.

• Setting up paste commands that cancel out to produce nothing will have differing results in the range-1 algorithm versus the general-range algorithm.
  • At T=0, in the range-1 algorithm, a dead cell is visible in the thumbnail, but is not present in the popup viewer; in the general-range algorithm, it is present in both cases. In both cases, dead cells will manifest from T=1 onwards.
  • The dead cells in the general-range algorithm, besides the first two, will never fade.
  • The entire grid setup shows that for the general-range algorithm, the entire board, besides a central 2x2 area, is affected. Drawing cells and then starting playback will cause interesting results.

• Attempting to customize the colour of GRIDMAJOR in a hexagonal or triangular rule, or a square grid rule with a GRIDMAJOR interval of 0, will not display an error.
  • This is unlike when trying to color cell states which do not apply to the active rule, as well as bounded grid edge cells in rules which do not specify a bounded grid; both cases produce an error to indicate that the customization is irrelevant.

• Changing the color of "dead" in [R]Super or [R]Investigator will not change the color of any cell states. However, it also will not display an error indicating that "dead" is not a valid element to customize for these specific rules.
  • In [R]Standard and [R]History, "dead" will affect the colors of freshly-dead cells.
  • Attempting to customize the capitalized "DEAD" in [R]Super or [R]Investigator will display an error.

• When changing the active theme, TRACKLOOP will not adjust, resulting in visual major grid line jumping.
  • For the following, change the theme to a theme with major grid lines such as the MCell theme.

• Pasting something in [R]History via PASTEMODE COPY will cause any state-0 cells to become freshly-created state 2 cells.
  • This is in contract to pasting state-2 cells themselves: these are set as fully aged.
  • Expected behaviour would be for state 0 cells to be pasted as state 0 cells.

• If a pattern that uses HISTORYFIT has its evolution modified by PASTE or Kill Gliders in a certain way, AUTOFIT will ignore all preceding history cells when calculating the box to fit the pattern to.

• User interfaces interact incorrectly with specific values for popup width and height as defined in script commands.
  • On some touchscreen devices, the popup created by the right thumbnail is twice the size it should be.
  • If a viewer window has a height of below 480, the Settings button will be disabled as the contents of that menu would not display in a usable way. Maximizing the popup on the right will enable that button, allowing it to be entered, and un-maximizing the popup will result in the settings menu closing. However, it may remain open for one frame before closing, showing buttons in an intersecting state.

• If some commands are provided with a value exceeding 2147483647, they will overflow, rather than rejecting the value as it is provided. This does not apply to all commands.
  • These values are presumably those which are handled as Uint32Arrays.

• When all cells die, hexagonal grids may sometimes behave differently to square and triangular grids when using AUTOFIT on pasted content.
  • In the following case, it zooms in to the bottom left of the grid, whereas the other two remain at their final position. The script commands are identical across all three.
